Seamless casing pipe vs ERW casing pipe

Seamless steel casing pipes-casing made of seamless steel pipe as raw material Seamless pipe refers to a steel pipe manufactured by four methods: hot rolling, cold rolling, hot drawing, and cold drawing. There is no weld seam on the pipe body itself. ERW casing pipe-casing made of electric welded pipe as raw material ERW pipe refers to a straight seam welded pipe manufactured through a high-frequency resistance welding process. The raw material steel

Anti-corrosion technical requirements for seamless pipes

Seamless steel pipe (SMLS) is the most widely used pipe material at present. Generally, it needs anti-corrosion treatment when it is used for chemical pipelines, oil pipelines, natural gas pipelines, water pipelines and other projects. The common anti-corrosion processes of seamless steel pipes mainly include 3PE anti-corrosion, Epoxy coal tar anticorrosion, epoxy resin anticorrosion, IPN8710 anticorrosion, cement mortar anticorrosion technology, etc. 1. Why is seamless steel pipe anti-corrosion? Seamless steel pipe is

What are the commonly used heat treatment processes for seamless steel pipes?

There are many varieties of steel pipes, and the steel grades (species) used are not the same. The chemical composition of the same variety of steel pipes may also be different, but after heat treatment, the steel pipes can meet the relevant technical standards or technical conditions of the purchaser. According to product standards, seamless steel pipe heat treatment processes mainly include the following five categories. (1) Quenching + high temperature

Technical Standards for Precision Seamless Hydraulic Tubes

What is precision hydraulic seamless steel tube? Precision seamless hydraulic tube made of precision cold drawn seamless steel tubes that are processed by black or gray phosphating process, and the phosphated steel tubes are sealed and rust-proofed.Hydraulic steel pipes are basically divided into fluid pipes and oil steel bobbins used in hydraulic systems, also known as honing pipes, and cold-drawn or cold-rolled precision seamless steel tubes also include hydraulic steel tube.
